Slide show: Common skin rashes

Ringworm of the body (tinea corporis) is a fungal infection that appears as itchy, red, scaly, slightly raised, rings on the body. The ring grows outward as the infection spreads, and the center area becomes less actively infected.

Ringworm often spreads by direct skin-to-skin contact with an infected person or animal. Treatment usually requires prescription antifungal medication that you apply to your skin.

A tinea infection in the groin is called jock itch (tinea cruris), and a tinea infection of the foot is called athlete's foot (tinea pedis).
